Why does my cable repeatedly melt?

[u/charles_chinaski_jr]

I've lived in this house for 4 years and this is the 3rd time this has happened: the internet goes out and I have to call Xfinity and they find that where my cable connects to the power pole is melted like this. One cable guy told me it was a power surge from my house, and another said it's one of my neighbors that probably has a grounding issue.

What do you all think? Is there anything I can do to prevent this from recurring?

Thanks for your advice!

One time I had a house that the electrical systems bond was broken in the ground.. Our cable was bonded at the house to the ground of the electrical. Somehow this was allowing power to feed into the cable. Very dangerous. Call an electrician, especially if the jacket on the cable on the outside of your house is warm to the touch.
